Is this an upgraded upper valve cover?

Looks like previous owner upgraded the lower covers but im not sure about the upper covers.
The part number is 901.105.115.2R anyone know if this is the one that doesnt leak?

I didn't know there was an upgraded upper cover. The lower cover is simply the turbo version which is stouter to handle the higher heat without warping.

Thanks mreid. Its all making sense now.

The aluminum Carrera uppers leak less than any mag upper. I consider that an upgrade.
